Atmosphere in the levels is great, controller is great, I just didn't notice where the theme came into play

As you wrote in the comment the theme was probably inside of the multiplayer element. It's fun and really popular gameplay but with  the cool atmosphere and the use of the low poly elements it give the whole game a polished feel. 

Nicely done! Despite the theme not really being included much I did love seeing the Simple assets come to life. I haven't tried the multiplayer side of it out though.

Got to Wave 5

Good Job!

Pretty cool, however at some point it seems the zombies just stop popping up.

I can see how with some more polishing, and a few more features around the room unluck it can be a quick grab on steam.

Keep at it!!

Had some fun for something like half an hour. Uops.
Couldn't really see where the "unlikely allies" theme would be used here. (Maybe in the characters skins?)
The game works kinda well, other than little pathfinding issues. But it's totally playable and enjoyable!

Typical FPS game, which I don't particularly like, but it's functional and I think you can have fun with friends. I didn't find any reference to the proposed theme.

Managed to fix the multiplayer in this version: https://drive.google.com/file/d/1VxeKGQhZmuBzQxkzByY-ATJ7WxblKqBc/view?usp=shari...
There is no differences other than this aforementioned fix, so if you don't intend to play on multiplayer you can use the download from above.

As per usual, in typical game-jam fashion at the last moment I seem to have broken the multiplayer functionality in the build which is available to download. 😡 So it's now very unlikely that you'll have any allies to play with 😡
